Hello, here I am again.  I found the solution to the problem.  The error occures because the installation isn't completed.  You should check if the user "NETWORK SERVICE" (on IIS6.0 on Win2003) or ASPNET (on IIS5 on WinXP and Win2000) have read-access to the root of the disk.  In the installation manual is nothing said about the read-permissions of the root of the disk, only about the root of the application.

My wwwroot folder is located on my D-disk of my webserver.  "NETWORK SERVICE" has no read permission on this disk (by default).  So, during installation, you have to set these permissions.

Of course, if you application folder is located in subfolders, NETWERK SERVICE should also have read-permission to those subfolders.

Hope this was helpfull for you all...
